/** Convert string content to numeric value.
    
    Converted are only integer numbers including exponent, and ISO 8601 dates 
    and times in their extended formats with separators. Anything else, 
    especially fractional numeric values with decimal separators or dates other 
    than ISO 8601 would be locale dependent and is a no-no. Leading and 
    trailing blanks are ignored.

    The following ISO 8601 formats are converted:

    CCYY-MM-DD
    CCYY-MM-DDThh:mm
    CCYY-MM-DDThh:mm:ss
    CCYY-MM-DDThh:mm:ss,s
    CCYY-MM-DDThh:mm:ss.s
    hh:mm
    hh:mm:ss
    hh:mm:ss,s
    hh:mm:ss.s

    The century CC may not be omitted and the two-digit year setting is not 
    taken into account. Instead of the T date and time separator exactly one 
    blank may be used.

    If a date is given, it must be a valid Gregorian calendar date. In this 
    case the optional time must be in the range 00:00 to 23:59:59.99999...
    If only time is given, it may have any value for hours, taking elapsed time 
    into account; minutes and seconds are limited to the value 59 as well.
